GAS-SCRUBBER.

Application filed February 12, 1913.

To all whom it may concern:

Be it known that I, HENRY A. CARPENTER, of Sewickley, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Gas- Scrubbers, of which the following is a specification.

The prime object of the present invention is to provide a new and improved gas scrubber, and more particularly a scrubber of this class especially designed for the extraction of ammonia from a gas current of illuminating gas that has been freed of certain foreign substances prior to reaching the gas scrubber.

In the accompanying drawings, which illustrate an application of my invention, Figure 1 is a vertical sectional view of. a scrubber embodying my invention, the section being taken on line-II of Fig. 2 looking in the direction of the arrows; Fig. 2 is a part side elevational and a part sectional view of the apparatus, the section being taken on line IIII of Fig. 1; Fig. 8 is an enlarged vertical sectional view taken through a set or bundle of scrubber plates;

Fig. 4 is a perspective view of several as sembled plates; and Fig. 5 is across section taken on line VV of Fig. 4.

As illustrated and as preferred, the scrubber comprises an annular casing 1 having a gas inlet opening 2 and a gas outlet opening 3, respectively adapted to be connected with a main 4through which the gaseous current travels on its way to a gas holder, not shown. The casing as shown comprises two side plates 5 formed with inwardly projecting flan ed portions 6, which latter portions are adapted to be connected by an annular plate 7.

Centrally disposed within the casing and designed to divide the casing into two compartments 8 and 9, is a partition wall 10, said partition wall being secured to the annular plate 7 by means of rivets 11.

Conveniently arranged in connection with the scrubber, is a water or other liquid supply pipe 12 having branches 13 respectively designed to supply a liquid to the interior of the chambers 8 and 9 for the purpose of providing a liquid-body as indicated by the numeral 14.

Located Within and extending transversely of the casing, I provide a hollow cylindrical member 15 having its respective Specification of Letters Patent.

ends mounted on enlarged portions 16 of stub shafts 17 and 18, with the ends of said shafts 17 and 18 located in roller bearings 19 secured to the opposite side plate members 5. Welded or otherwise secured to member15 1s a series of annular plates 20, 21, 22 and 23. These plates are preferably formed of a plurality of sections welded together and are arranged in pairs, with one pair located in chamber or compartment 8 and the other pair located in chamber or compartment 9. Each pair constitutes an annular pack frame into which is placed a series of radially disposed plates 24 dividing the frame into a series of compartments 25, with each compartment adapted to receive a pack or bundle of separable scrubber plates 26.

The inner plates 21 and 22 of the respective annular frames are each respectively formed with an annular opening 28 and 29 deslgned to permit the passage of the gaseous current from chamber 8 into chamber 9, and in order to prevent the passage of the gaseous current up between the two annular frames, l[ provide a flanged ring 30 secured to the respective inner members 21 and 22 by rivets 31.

In order to permit the scrubber plates 26 to be inserted in and removed from the sev eral compartments 25, the annular band 7 is formed with openings 32 as particularly shown by Fig. 2. lhese openings are closed by a cover plate 33 adapted to be secured to the annular plate 7 by means of bolts 34.

The scrubber or pack plates 26, as preferred, are particularly shown in Figs. 4 and 5. As shown, each plate has its side edge portions bent upon the body portion of the plate, the overlapping part of one edge, as a, for instance, being on the opposite side of the plate from the overlapping portion at the other side edge, the latter being shown at b. As a result, the overlapping portions a and 6 form spacing elements when the plates are assembled in pack form, the elements of a plate having a. contact with the body portion of plates between which it is positioned. In addition, predetermined portions of the body of the plate are bent to form openings and overlapping portions adjacent the openings, these being indicated at c, and also form additional spacing elements through their locations on opposite sides of the plate. Since the overlapping portions, in the embodiment shown herein,

are formed integral with the space and the overlapping portions are provided by bending the plate material so as to place the overlapping portions in facial contact with the bod of the plate, it will be readily understoo that the spacing of the plates will be uniform and will also, by reason of the particular locations of the spacing elements, retain the plates in position against relative rocking movements, so that when the plates are in position, the channels therebetween will be substantially uniform.

The bundles or packs of separable plates 26 are locked in the respective compartments 25 by spring controlled locking members 35, the latter members being adapted to project outwardly from a sleeve 36 and have their square ends entered in square openings in the plates 21, 22, 23 and 24 of the two annular frames, and the scrubber plates are each provided with a curved nick or slot 37 adapted to receive the sleeve 36. When it is desired to remove the plates 26 for the purpose of cleaning said plates, a bundle or pack is brought into register with an opening 32, and the spring 38 controlling members 35 is compressed sufiiciently to permit the ends of members 35 to be withdrawn from the square openings, thereb permitting the plates to be lifted out in ividually through an opening 32 in the annular plate 7 The revoluble hub or member 15, together with the frames and the series of bundles .of scrubber plates, may be rotated b any suitable means, as for example, an e ectric motor. As illustrated, shaft 18 is provided with a gear wheel 39, and this wheel meshes with a ear 40 mounted on a shaft 41, which latter siaft is also rovided with a wormwheel 42. Worm-w1eel 42 is driven by a worm-shaft 43, the latter being driven by an electric motor, not shown.

The gaseous current entering the apparatus through the gas inlet is caused to pass down through the rotating bundles or packs of scrubber plates 26 located in chamber 8, and from said chamber through openings 29 and 30 into chamber 9. The current enter ing chamber 9 then passes u wardly through the various revolving bund es in chamber 9 to the main 4 through the gas outlet 3.

What I claim is 1. In a as scrubber, a casing having supply and dlscharge openings, an annular division plate secured to the casing, a rotatable member mounted in the casing and carrying airs of annular plates, said airs being coated on opposite sides of t e division plate, the inner plate of each pair having a series of openings, an annular member connectin the inner plates of said pairs and locate between said plate openings and the inner edge of said division plate, means for forming pack-receiving compartments between the plates of each pair, and pack plates supported in the several compart ments and individually insertible therein.

2. In a gas scrubber, a pack carrier having pack-receiving compartments, individual pack plates, and means for securing the plates in packrelation within the compartments, said means permitting positioning and withdrawal of the plates individually.

3. In a gas scrubber, an annular pack carrier having fixedly positioned packreceiving compartments, individual pack plates, and means for securing the plates in pack relation within the compartments, said means permitting positioning and withdrawal of the plates individually.

4. In a gas scrubber, a pack carrier having pack-receiving compartments, individual pack plates, and means for securing the plates in packrelation within the compartments, said means being positionable independently of the pack plates and permitting ositionin and withdrawal of the plates lndividua y.

5. In a gas scrubber, a pack carrier having pack-receiving compartments, individual pack plates, and means for securing the plates in ack relation within the compartments, said means comprising a device for each pack cooperating with the compartment walls and positionable independently of the pack plates, said means ermitting positionmg and withdrawal 0? the plates in dividually.

6. In a gas scrubber, a pack carrier having pack-receiving compartments, individual pack plates, and means for securing the plates in pack relation within the compartments, said means comprising a latching device for each pack cooperating with the compartment walls and positionable independently of the pack plates, said means permitting positioning and withdrawal of the plates individually.

7. In a gas scrubber, a pack carrier having pack-receiving compartments, individual pack plates, and means for securing the plates in pack relation within the compartments, said means comprising a spring-actuated latching device for each .pack cooperating with the compartment walls and positionable independently of the pack plates, said means permitting positioning and withdrawal of the plates individually.
